MECHANICAL MUSICAL INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 450,257, dated April14, 1891.

Application filed December 9, 1890. Serial No. 374,109. (No model.)

To all whom it may concern:

Beit known thatI, ERNST SOHILLING,L SU1)- jcct of the German Emperor,residing at Leipsic, in thcEmpire of Germany, have in vented a certainnew and useful Improvement in Mechanical Musical Instruments, of whichthe following is a specification.

This invention relates to mechanical musical instruments; and itconsists in an im proved arrangement therein of an improved pin-wheelbymeans of which the sound-producin g devices may be operated by asuitabl yslotted m usic-sheet, the improved pin-wheel being suitable,according to its size, for mu sical boxes in which sounds are producedby vibrating metal tongues, as well as for those instruments in whichsounds are produced by pipes, reeds, or strings, or other soundingdevices, the controlling-valves, pallets, or hammers or equivalents ofwhich are arranged to be operated by the passage of a pin or projectionfor moving them or for combinations of these.

The accompanying drawings illustrate the improved pin-wheel mounted in amusical box with vibrating metal tongues, Figure 1 being a frontelevation of the mechanism, partlyin section; Fig. 2, a plan thereof; Fi3, a section on line C D, Fig. 2; Fig. 4, a similar section illustratingthe pin-wheel as applied to the operating of two separate sets ofsound-producers. Figs. 5 to8 are detail views of parts, Fig. 5 being anelevation, and Fig. 6 a section, of a disk for holding the pins; Fig. 7,a spring for protruding the pins; Fig.8, one of said pins on thepin-wheel. Fig. 9 is a side elevation, partly in section; and Fi 10 is across-section illustrating a modified henceforth the respective disk isrotated by the music-sheet for a distance sufficient to cause another orothers of the system of pins thereon to vibrate the respective soundingtongue or tongues which the system is arranged to operate.

This invention may be carried out as follows: The disks informing thepin-wheel n", are arranged to rotate on the tube 7e independently onefrom the other, said tube being placed over the rotating shaft 0.. Inorder that during the rotation of the shaft a the tube 7c is notrotatedthat is, carried along in the same direction by the frictioncaused by the surface of the tube It; being in contact with that of theshaft a-a stop'lever g is arranged on the tube 7c in firm connectiontherewith. Said lever, as shown by Figs. 3 and 4, rests upon thebase-plate p of the work, and thus prevents the tube 7a from rotating.The disks or are of equal diameter and similar perforation andtheirseveral thicknesses equal to the distaiice from center to center ofthe steel tongues of the comb h, from which the sounds are obtained.

On one side, as shown by Figs. 5 and 6, the disks n are centrallyrecessed at n to receive a circularly-bent spring 9, Fig. 7, in therecess of each disk 11. Besides, as shown in Fig. 5, the disks a areprovided on the said side at equal distances with a number of radialslots n extending from the periphery to the said central recess. In eachof said slots a pin .9, Fig. 8, with a bent end, is placed in such amanner that the bent ends of all the pins .9 of each disk n are locatedin the central recess of the same and are pressed by the spring 7*against the edge of said recess. The pins .9 are all of the same length,and the recesses of the disks n are also of equal diameter, so that thepins 5 project at equal height from the circumference of the disks or.The disks n are placed close to one another upon the tube k, and a plainclosing disk is placed against the disk it placed last over the tube71:, so that the notches and the recess of each disk n are covered byneighboring disk, and the pins 3 and the spring 0" are retained in theirplaces.

The notes of the music-sheet m are formed by perforating or recessing,and therefore the music-sheets are without any elevations.

The modification shown more particularly in Fig. differs, in that thecentral recess a of each disk is made deep enough only to receive tailsof the pins 3. A groove is made arounda part of the circumference of thetube It, and springs are fixed atone end in said groove to press outwardthe pin or pins of each disk at the place where they engage with themusic-sheet. In Fig. 11 a similar construction is shown; but the spring7' is here a double spring, one part acting to protrude the pins at theplace of their engagement with the musicsheet and the other acting uponthe pins at the place where they are required to be protruded to engagewith the comb.

The musical box provided with this improvement operates as follows: Theshaft a, passing through the pin-wheel n, is operated in the usualmannerby the spring-workfand wheels I) and c; likewise thewind-regulatorby the shaft a, wheel 0, and usual train of wheels. On theshaft a are two wheels d, which gear with the music-sheet m and carrythesame along over the cylinder n. During the sliding of the music-sheetan over the cylinder 77. all the pins 5, which are in contact with themusicsheet 111, are slightly pressed toward the interior of thepin-wheeln, as longas no note-that is, no-hole of the music-sheet mhasarrived over any of them, (see Fig. 4;) but as soon as a note arrivesabove one of the pins 8 (see Fig. 3) the respective pin 5 jumps into thehole: of the music-sheet m in consequence of the spring 0' acting uponsaid pin 8, and the latter is carried along by the music-sheet m, sothat at the same time the disk a, holding the pin s, rotates on the tube7;,and the pin 3 is carried along until it is withdrawn again from thenote-hole by the rotation of the disk. During this rotation of the disk41 a second pin 8 ofthe same disk passes at the same timea tongue of thesteel comb h, and causes asouud thereby. If several pins 8 of differentdisks jump simultaneously into different note-holes, several disks n arerotated by the same on the tube It, and consequently several sounds arecaused simultaneously by the tongues of the steel comb h. Thus with asuitable arrangement of the note holes on the musicsheet m any piece ofmusic may be played on this musical box.

In order to produce as many sounds as possible by a pin-cylinder thusconstructed, one may bring two or more steel combs into contact with thepin-wheel n, as seen by Fig. i. In a similar manner as for musical boxesthus described this new device may be used also for musical boxes orworks inwhich the sounds are obtained direct from the strings or plates,&c., or by means of wind from tongues and pipes, the pins being causedon the rotation of the disks or, moved by the music-sheet, to set inmotion in a suitable manner the operating mechanism for producing thesound from the respective strings or plates, &e., or the windvalvesleading to the tongues or pipes.

I claim in a mechanical musical instrument- 1. The combination,substantially as and for the purpose set forth, with a series of sound-preducers and a movable slotted musicsurface, of a pin-wheel consistingof a series of independen tly-revoluble disks with springprotrudedequidistant projections on their circumferences.

2. The combination, substantially as am for the purpose set forth, witha series of sound-producers and a movable slotted music-surface, of apin-wheel consisting of a series of independently-revoluble disks, acircular central recess in the one face of each disk, a series ofequidistant slots in the periphery of each disk, movable pins 8 in saidslots, anda spring r in the central recess of each disk.

3. The combination, with two or more series of sound-producers and amovable slotted music-surface, of a pin-wheel consisting of a series ofindependently-revoluble disks with spring-protruded, equidistantprojections on their circumferences, adapted to be revolved by saidmusic sheet, and thus operate respective sound-producers,substantiallyasset forth.

4. The combination of one or more series of sound-producers, a movableslotted musicsheet, a central shaft at, having wheels (Z (Z for movingsaid music-sheet, a stationary tube 71', on said shaft, a series ofindependent rotary disks n on said tube, with equidistantspringprotruded projections on their peripheries, adapted to operate inconnection with the music-sheet and sound-producers, substantially asset forth.

In witness whereof I have signed this specification in presence of twowitnesses.
